| Abstract: | The task of the magnetotelluric (MT) sounding of the heterogeneous deep section of the Arctic ocean floor on the idealized
model of gorst and graben lying on the typical oceanic, or continental Earth’s, crust is solved with the use of 3D quantitative
modeling. In both cases, the sequence is covered by a layer of seawater with a thickness of 4 km. In this work, the difference
in the MT sounding with the use of ocean-floor and surface equipment is considered. As a result, the conclusion was made that
the floor equipment has a higher resolution than the surface equipment, in spite of the fact that the observations from the
ice cover’s surface can be done more easily. |
